Explore the beauties of the night sky with this complete telescope set. Everything is included so that you can get started immediately with the fascinating hobby of astronomy: the astronomical reflector telescope with 150 mm aperture and 1,400 mm focal length, the equatorial mount, the tripod and extensive accessories for exciting observations. Especially important for beginners: the system is very easy to use. Particularly the Moon, the planets and the Sun appear impressive through the Pollux-II. Powerful performance for your first celestial observations – the telescope Take your first steps in astronomy with this classic reflector telescope of the "Newton" type. Because it is equipped with an additional lens inside the focuser, it belongs to the group of the so-called "catadioptric" optics. One advantage of this combination of lens and mirror: despite the large focal length, the telescope tube is relatively short and therefore easily transportable. In addition, you can look forward to a comfortable observation position at all times. This is because with telescopes of this design you do not look in at the back of the telescope, but at the front and laterally. So you don't have to bend down, even if the reflector telescope is pointed vertically upwards at the sky. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 1,400 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 9.3 (F/9.3). This allows you to enjoy viewing your favourite objects at high magnifications with good contrast. Admire especially the planets or details on the Moon through the entry-level telescope. But also some deep sky objects are very nice to observe: open star clusters, globular clusters and bright planetary nebulae such as the Ring Nebula M57 in the constellation Lyra can be seen beautifully through this astronomical telescope. But how close can you get to the celestial eye-catchers? The 150 mm aperture achieves a resolving power that allows magnifications of up to 300x with sharp images. The technical possibilities go far beyond this – theoretically up to 1,050x using the included accessories. However, as the magnification increases, the sharpness of the image can slowly decrease. In addition, high magnification also requires the right environmental conditions. For no matter through which telescope you look, the air turbulence in the atmosphere (seeing conditions) always influences your observation and magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-II reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. Solid base for gazing skywards – mount and tripod Have you found the perfect location for your journey of discovery into the night sky? Then simply mount your astronomical telescope with the equatorial mount on the height-adjustable aluminium tripod. The special feature of this type of mount: after the so-called "alignment", the positioning of an axis parallel to the Earth's axis, the movement of the celestial bodies only has to be compensated for on this one axis. To do this, you simply point the axis approximately at Polaris. This is a huge advantage over the azimuthal mount, where both axes are moved simultaneously. In addition, the two flexible shafts with fine adjustment make adjusting and tracking the telescope very precise and comfortable. And to ensure that accessories are always at hand, they can be stored on the handy shelf between the tripod legs.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Everything you need, night and day – the accessories The astronomical telescope comes with a wide range of equipment so that you can start admiring the Moon, planets or the Sun straight away. At night, the LED viewfinder helps you keep an overview of the sky. Once installed parallel on the tube and correctly aligned, the small red dot shows you where the telescope is pointing when you look through it. This way, you can align the optics precisely and find celestial bodies more quickly before you then take a closer look with the high magnification. Varying views of the universe: the two eyepieces allow you to marvel at your observation objects in different magnifications. They are simply inserted into the telescope's focuser using their sockets with a standardised 1.25 inch (31.7 mm) diameter. You want to see even more details? Then go for the 3x barlow lens, which triples the magnification of the eyepieces. If you would like to make astronomical discoveries even during the day, use the solar filter to observe the star of our own solar system. It allows you to easily and safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Capture special highlights easily – with the smartphone adapter, you use your smartphone as a camera for your telescope. This way you can quickly take your first photos of the Moon or the Sun, for example, and get started in astrophotography. FEATURES Reflector telescope with 150 mm aperture and 1,400 mm focal length Reflector type catadioptric Well suited for observing the Sun, Moon and planets Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, very suitable for beginners Focal ratio F/9.3, therefore good for observing the planets and details on the moon 1.25 inch (31.7 mm) eyepiece focuser Two eyepieces and one barlow lens with 1.25 inch (31.7 mm) extension tubes for different magnifications Safe solar observation with the included solar filter Entry into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual

Who doesn't dream of exploring the beauties of the universe with their own eyes? This complete telescope set allows you to make your first celestial observations immediately and very easily. It contains everything you need for your new hobby: a reflector telescope with 130 mm aperture and 650 mm focal length, an equatorial mount, a tripod and extensive accessories for astronomical observations. The system is easy to operate and very flexible. You can look forward to fascinating views of the Moon and planets. Star clusters and gas nebulae also look impressive through the user-friendly entry-level telescope. Easy start with the astronomy all-rounder – the telescope The set includes a true classic among the reflector telescopes, a so-called Newtonian reflector. With this type of telescope, you look in at the front of the tube instead of at the back. The advantage: the observing position always remains comfortable, even when the telescope is pointed vertically upwards. In addition to observing comfort, reflectors also impress with their optical performance. After all, they are absolutely free of chromatic aberrations and thus offer good imaging properties. Due to its 130 mm aperture, the entry-level telescope already collects a lot of light from the celestial objects. In addition, there is the short focal ratio (ratio of the aperture to the focal length) of 1 to 5 (F/5), which derives from the 130 mm aperture and the 650 mm focal length. As a result, the fast beginner's telescope shows a bright image and enables high magnifications. You also benefit from the flexibility of this astronomical telescope: Admire the fascinating view of open and globular clusters such as M13 in the constellation Hercules at low to medium magnification. Or marvel at gas nebulae such as the famous Orion Nebula M42. At high magnifications, on the other hand, the entry-level telescope brings you closer to the impressive planets and exciting details on our Moon. How big do the astronomical eye-catchers appear? Due to the resolving power achieved with the aperture of 130 mm, the telescope shows you sharp images at magnifications up to about 260x. With the included accessories, you can already reach 195x. The technology allows even more, but the image sharpness can decrease at even higher magnifications. However, it is not only the telescope that determines how much you can magnify. It also depends on the air turbulence in the atmosphere (seeing conditions). Note for nature lovers: If you choose a Newtonian telescope like the Pegasus reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. User-friendly base – mount and tripod Found the perfect place for your celestial observations? Then you can start installing your astronomical telescope on the height-adjustable stainless steel tripod with equatorial mount. The advantage over azimuthal mounts: you only have to move along one axis instead of two. The reason is that you align the other one parallel to the earth's axis beforehand. This so-called "alignment" is very easy: you simply point the axis approximately at Polaris. In addition, the mount comes equipped with two flexible shafts with fine adjustment. Perfect for aligning and tracking the telescope particularly precisely and comfortably. Everything always within reach: on the practical storage plate, your accessories are quickly at hand if needed.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Complete astro package to start stargazing immediately – the accessories The comprehensive astronomy accessories make it easier for you to get started and enable you to see your favourite celestial bodies from completely different perspectives. To align the telescope and find your way around the night sky you can mount the LED finder parallel to the telescope. The method is simple: a red dot is projected onto a small ground-glass screen inside the viewfinder. When you look through the dot appears to hover in front of the sky – exactly at the point where the entry-level telescope is pointed. This way, you can easily find astronomical objects through the illuminated dot finder and then marvel at them in detail using the high magnification of your telescope. Vary your view of the stars: with the two eyepieces (10 mm and 25 mm), you can admire your nocturnal observation objects in two different magnifications. They are simply inserted into the eyepiece focuser of the telescope via their 1.25-inch-sockets, which is a standard diameter. You want to look even closer? Then the included 3x barlow lens can triple the magnification of the eyepieces. Explore the night sky on your own through the versatile BRESSER Pegasus 130/650 EQ3 reflector telescope. FEATURES Reflector telescope for beginners with 130 mm aperture and 650 mm focal length Reflector type: Newton Good for observing Moon, planets as well as star clusters and gas nebulae Height-adjustable tripod with equatorial EQ3 mount Precise positioning due to flexible shafts and fine adjustment in both axes Easy to use, very well suited for beginners Focal ratio F/5, thus well suited for many celestial objects 1.25 inch (31.7 mm) focuser Two eyepieces and a barlow lens with 1.25 inch (31.7 mm) sockets for different magnifications SCOPE OF DELIVERY Telescope Stainless steel tripod Equatorial EQ3 mount Eyepieces: 10 mm and 25 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Accessory tray Astronomy software download Instruction manual
